Indeed, a module of code may be a single instruction, or manyinstructions, and may even be distributed over several different codesegments, among different programs, and across several memory devices.Similarly, operational data may be identified and illustrated hereinwithin modules, and may be embodied in any suitable form and organizedwithin any suitable type of data structure. The operational data may becollected as a single data set, or may be distributed over differentlocations including over different computer readable storage devices.Where a module or portions of a module are implemented in software, thesoftware portions are stored on one or more computer readable storagedevices.

Any combination of one or more computer readable medium may be utilized.The computer readable medium may be a computer readable storage medium.The computer readable storage medium may be a storage device storing thecode. The storage device may be, for example, but not limited to, anelectronic, magnetic, optical, electromagnetic, infrared, holographic,micromechanical, or semiconductor system, apparatus, or device, or anysuitable combination of the foregoing.

More specific examples (a non-exhaustive list) of the storage devicewould include the following: an electrical connection having one or morewires, a portable computer diskette, a hard disk, a random access memory(“RAM”), a read-only memory (“ROM”), an erasable programmable read-onlymemory (“EPROM” or Flash memory), a portable compact disc read-onlymemory (“CD-ROM”), an optical storage device, a magnetic storage device,or any suitable combination of the foregoing.

In such embodiments, analog beams associated withdifferent TRPs or panels may be used to transmit data packetssimultaneously and beams belonging to the same TRP or panel can't beused to transmit data packets simultaneously. Therefore, multiple beamsfrom multiple TRPs or panels may be used to transmit the same datapacket with different redundancy versions simultaneously to a UE toincrease the robustness of a DL transmission while, at the same time,not increasing latency when compared to a single transmission. It shouldbe noted that a panel may have multiple antennas controlled by onecontroller to perform analog beamforming.

In some embodiments, a TRP may be part of a basestation.

In one embodiment, multiple TRPs and/or panels of a single gNB may havean ideal backhaul or low latency backhaul. In such an embodiment, onePDCCH may be used to schedule transmission of the same TB with differentredundancy versions and transmitted from multiple TRPs and/or panelswith multiple TX beams to a UE (e.g., remote unit 102) in one timeduration (e.g., a basic time unit, a symbol, a slot, a subframe, ahalf-frame, and/or a frame) using FDM. Furthermore, in such embodiments,the UE may be able to receive multiple TX beams simultaneously using asingle panel. In certain embodiments, the UE may receive multiple TXbeams simultaneously using multiple panels. In various embodiments, anumber of RX beams may be equal to a number of UE panels. It should benoted that at most one RX beam may be used per UE panel and that RX beammay be used to receive multiple TX beams. In some embodiments,information indicating which beams can be received simultaneously by aUE may be obtained by a group based beam reporting via beam management.

The first TRP 502transmits a first TX beam 512 and the second TRP 504 transmits a secondTX beam 514. A first panel 516 of the UE 510 receives the first TX beam512 and the second TX beam 514 using a first RX beam. The third TRP 506transmits a third TX beam 518 and the fourth TRP 508 transmits a fourthTX beam 520. A second panel 522 of the UE 510 receives the third TX beam518 and the fourth TX beam 520 using a second RX beam.

In one embodiment, each TB of multiple TBs occupies the same time domainallocation and has the same number of RBs in the frequency domainscheduled by a single DCI that is transmitted in a PDCCH. As may beappreciated, all of the TBs of the multiple TBs may contain the samedata that is varied using a redundancy version. In some embodiments, asingle field of frequency domain resource assignment in DCI may be usedto indicate the frequency allocation of each TB of the multiple TBs.

In some embodiments, there may be two types of DL frequency allocationto indicate a frequency allocation of a single TB. In variousembodiments, the two types of DL frequency allocation may be describedin TS 38.214 5.1.2.2.1 and 5.1.2.2.2. Both of the two types of frequencyallocation may indicate VRB allocation for DL transmission while thereis a one to one mapping between VRB and PRB. As described herein,frequency resource allocation may be indicated as allocating VRBs. Thismay be the equivalent to allocation of physical RBs because one VRB maybe mapped to one physical RB.

In one embodiment, a bitmap indication scheme may be used in which atotal number of ‘1’ bits, represented by N in a bitmap, may indicate amultiple of a number of times a TB (e.g., having a corresponding numberof VRBs) is repeated (“N_(rep)”), with each TB occupying N/N_(rep)continuous RBGs indicated by the bitmap by an increasing order of theRBG index. As may be appreciated, the continuous occupied RBGs (e.g.,indicated with a ‘1’ bit) may not be in adjacent frequencies becausethere may be one or more unoccupied RBGs (e.g., indicated with a ‘0’bit) between the continuous occupied RBGs.

For example, if a bitmap in a DCI used to indicate frequency allocationis set to “011011101110” with a total of 8 bits set to a value of ‘1’,i.e., N=8, and we assume there are 12 RBGs in a BWP (e.g., asillustrated in FIG. 6) with a single TB being repeated four times fortransmission at the same time, i.e. N_(rep)=4, then this means that eachTB occupies 2 RBGs, i.e., N/N_(rep)=2.

FIG. 6 is a schematic block diagram illustrating one embodiment ofresource allocation 600. The resource allocation 600 includes a firstRBG 602, a second RBG 604, a third RBG 606, a fourth RBG 608, a fifthRBG 610, a sixth RBG 612, a seventh RBG 614, an eighth RBG 616, a ninthRBG 618, a tenth RBG 620, an eleventh RBG 622, and a twelfth RBG 624 alltransmitted in one time duration 626 (e.g., a basic time unit, a symbol,a slot, a subframe, a half-frame, and/or a frame) and over a frequencyrange 628. The first RBG 602 corresponds to a first bit in a bitmap, thesecond RBG 604 corresponds to a second bit in the bitmap, the third RBG606 corresponds to a third bit in the bitmap, the fourth RBG 608corresponds to a fourth bit in the bitmap, the fifth RBG 610 correspondsto a fifth bit in the bitmap, the sixth RBG 612 corresponds to a sixthbit in the bitmap, the seventh RBG 614 corresponds to a seventh bit inthe bitmap, the eighth RBG 616 corresponds to an eighth bit in thebitmap, the ninth RBG 618 corresponds to a ninth bit in the bitmap, thetenth RBG 620 corresponds to a tenth bit in the bitmap, the eleventh RBG622 corresponds to an eleventh bit in the bitmap, and the twelfth RBG624 corresponds to a twelfth bit in the bitmap. Using the bitmap exampledescribed herein (e.g., bitmap of “011011101110”), a first TB istransmitted in the second RBG 604 and the third RBG 606, a second TB istransmitted in the fifth RBG 610 and the sixth RBG 612, a third TB istransmitted in the seventh RBG 614 and the ninth RBG 618, and a fourthTB is transmitted in the tenth RBG 620 and the eleventh RBG 622. Each ofthe first TB, the second TB, the third TB, and the fourth TB includesthe same data that may be varied based on a redundancy version.

In some embodiments, the first RBG 602 and the twelfth RBG 624 (e.g.,the last RBG) may have different RB lengths than other RBGs in a BWP,therefore, the first RBG 602 and the twelfth RBG 624 may not be used totransmit TBs.

In certain embodiments, each TB occupies an equal length of continuousRBs in a frequency domain and the same time allocation in one timeduration, and a number of RBs between two consecutive TBs is same asillustrated in FIG. 7. In such embodiments, a RIV may be used toindicate a start frequency of a RB and a number of RBs in the frequencydomain.

FIG. 7 is a schematic flow chart diagram illustrating another embodimentof resource allocation 700. The resource allocation 700 includes a firstdata block 702 (e.g., first TB), a second data block 704 (e.g., secondTB), a third data block 706 (e.g., third TB), and a fourth data block708 (e.g., fourth TB) all transmitted in one time duration 710 (e.g., abasic time unit, a symbol, a slot, a subframe, a half-frame, and/or aframe) and over a frequency range 712 (“L′_(RB)”). Each of the firstdata block 702, the second data block 704, the third data block 706, andthe fourth data block 708 may carry the same data that may be redundantbut may vary based on a redundancy version. Furthermore, each of thefirst data block 702, the second data block 704, the third data block706, and the fourth data block 708 occupies a set of virtual resourceblocks 714 (“L_(RB)”) in a frequency domain (e.g., a set of consecutivevirtual resource blocks, each set of virtual resource blocks has a samenumber of consecutive virtual resource blocks). Moreover, a frequencyoffset 716 (“Offset_(RB)”) (e.g., number of virtual resource blocks usedto separate transmitted data blocks) is the same between two adjacentdata blocks. As may be appreciated, the frequency range 712 equals thesum of the four sets of virtual resource blocks 714 and the threefrequency offsets 716. A starting frequency 718 (“Start_(RB)”) indicatesa frequency at which the first data block 702 (e.g., the lowestfrequency RB) starts.

In some embodiments, the number of the repeated TBs transmitted in thetime duration 710 may be N_(rep) and may be configured by high layersignaling, and the Offset_(RB) may be indicated to a UE by high layersignaling or in L1 signaling (e.g., PDCCH).

In some embodiments, there may be at least two embodiments used toindicate the resource allocation 700 illustrated in FIG. 7 (e.g., viaDCI). In a first embodiment, a field for frequency domain resourceassignment in DCI may indicate the starting frequency 718 (e.g.,Start_(RB)) and the set of virtual resource blocks 714 (e.g., L_(RB)) ofthe TB (e.g., the first data block 702) with the lowest RB in thefrequency domain. In a second embodiment, a field for frequency domainresource assignment in DCI may indicate the starting frequency 718 andthe frequency range 712 (e.g., L′R_(B)). In certain embodiments, theremay be a relationship between L′_(RB) and L_(RB) which is represent asL′R_(B)=(N_(rep)−1) Offset_(RB)+N_(rep)L_(RB), the first and secondembodiments described may have equal function in indicating thefrequency allocation of multiple TBs.

In certain embodiments, a CSI-RS or an SSB resource may be used toindicate a DL TX beam of a gNB, and an SRS resource may be used toindicate a UL TX beam of a UE. As may be appreciated, because a beampair (e.g., mapped TX beam to RX beam) may be obtained by beammanagement, a UE may know which RX beam should be used for receivinginformation if a CSI-RS or an SSB resource is used to indicate a TXbeam. In some embodiments, an SRS resource may indicate an UL TX beam.Therefore, because there is a one to one mapping between a TX beam andan RX beam for the UE, the UL TX beam may implicitly indicate the DL RXbeam. Described herein are two examples used to indicate beaminformation transmitted to UEs for multiple simultaneous TBtransmissions over multiple TX beams from multiple TRPs and/or panels.

In one embodiment, a CSI-RS resource set or an SSB resource set,respectively, including all the CSI-RS resources or all the SSBresources that represent the TX beams, are used to transmit multiple TBssimultaneously as resource RSs of a TCI indicated in DL DCI orconfigured by RRC signaling to indicate the beam information.

For example, assume that a first CSI-RS resource, a second CSI-RSresource, a third CSI-RS resource, and a fourth CSI-RS resourcerepresent the first TX beam 412, the second TX beam 414, the third TXbeam 416, and the fourth TX beam 418 respectively in FIG. 4, or thefirst TX beam 512, the second TX beam 514, the third TX beam 518, andthe fourth TX beam 520 respectively in FIG. 5, then the CSI-RS resourceset includes the first CSI-RS resource, the second CSI-RS resource, thethird CSI-RS resource, and the fourth CSI-RS resource and may beconfigured as the resource RSs of the TCI.

In another embodiment, an SRS resource set including at most one SRSresource per UE panel to indicate one or more RX beams to receivemultiple TBs simultaneously transmitted using multiple TX beams. In oneembodiment, there are three methods used to indicate the RX beaminformation using the SRS resource set. In a first method, the SRSresource set may be used as an RX beam indication in RRC signaling.Moreover, in a second method, the SRS resource set may be used as aresource RS of a TCI field in DL DCI. Furthermore, in a third method,the SRS resource set may use an SRI in DL DCI to indicate the DL RXbeam.

For example, if a first SRS resource set corresponds to an RX beam inFIG. 4, e.g., a first SRS resource, then the first SRS resource set thatincludes the first SRS resource is used to indicate the RX beam usingone method described herein. As another example, if a second SRSresource set corresponding to a first RX beam and a second RX beam inFIG. 5, e.g., a first SRS resource and a second SRS resourcerespectively, then the second SRS resource set that includes both thefirst SRS resource and the second SRS resource is used to indicate theRX beams using one method described herein.

In some embodiments, an SRS resource set used to indicate the RX beaminformation may be configured by high layer signaling to indicate thatthe usage of the SRS resource set is for DL transmission beamindication.

In one embodiment, an index n (e.g., n=0, . . . , N_(rep)−1) of TBrepetitions is increased with an occupied RB index for all the TBrepetitions in the frequency domain. In some embodiments, each TB mayhave a redundancy version indicated to facilitate decoding of the TB bya UE.

In certain embodiments, multiple redundancy version sequences may beconfigured via high layer signaling (e.g., via RRC signaling), and aredundancy version field in the DCI may be used to indicate one of theredundancy version sequences.

For example, 4 redundancy version sequences may be configured for a UEvia RRC signaling in a time duration as shown in Table 1, and two bitsin the redundancy version field in DCI may be used to indicate whichsequence in Table 1 should be used. FIG. 8 shows the RV value of eachrepetition if the RV ID in the DCI field is set as ‘01’ according to theRV sequence configuration in Table 1. In another example, 4 redundancyversion sequences may be configured for a UE via RRC signaling inanother time duration as shown in Table 2, and two bits in theredundancy version field in DCI may be used to indicate which sequencein Table 2 should be used. FIG. 9 shows the RV value of each repetitionif the RV ID in the DCI field is set as ‘11’ according to the RVsequence configuration in Table 2.

Specifically, FIG. 8 is a schematic flow chart diagram illustrating afurther embodiment of resource allocation 800. The resource allocation800 includes a first data block 802 (e.g., first TB), a second datablock 804 (e.g., second TB), a third data block 806 (e.g., third TB),and a fourth data block 808 (e.g., fourth TB) all transmitted in onetime duration 810 (e.g., a basic time unit, a symbol, a slot, asubframe, a half-frame, and/or a frame) and over a frequency range 812.The first data block 802 has an RV=0, the second data block 804 has anRV=0, the third data block 806 has an RV=3, and the fourth data block808 has an RV=3.
